If you live in a state where the outcome of the presidential election is not in doubt, then voting for a third-party candidate is a sensible idea.
And when enough people in that "safe" state vote for a third-party candidate, suddenly the state isn't quite so "safe" any longer. Remember Brexit?
In an interview on BBC’s Victoria Live, one man who voted "Leave" said, "I didn’t think my vote was going to matter too much because I thought we were just going to remain."
The man, who was introduced as Adam, said he is now "worried" because he assumed "Remain" would win. He added, "I think the period of uncertainty that we’re going to have for the next couple of months — that’s just been magnified now. So yeah, quite worried."
In 1977, Diffie and Hellman proposed a machine costing an estimated US$20 million which could find a DES key in a single day. By 1993, Wiener had proposed a key-search machine costing US$1 million which would find a key within 7 hours.
One of the more interesting aspects of COPACOBANA [a DES cracking machine] is its cost factor. One machine can be built for approximately $10,000. The cost decrease by roughly a factor of 25 over the EFF machine is an example of the continuous improvement of digital hardware—see Moore's law. Adjusting for inflation over 8 years yields an even higher improvement of about 30x.
DES hasn't changed, but the amount of computational power attackers can bring to bear has.
Or to put it a different way: archers manning a castle's walls were a decent defense against melee soldiers
